This test also restarts one of > the datanodes in the MiniDFS cluster just like testRecover() and it somehow > causes the failure. > {noformat} > java.lang.AssertionError: flush should fail > at org.junit.Assert.fail(Assert.java:89) > at > org.apache.hadoop.hbase.io.asyncfs.TestFanOutOneBlockAsyncDFSOutput.testRecover(TestFanOutOneBlockAsyncDFSOutput.java:154) > at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method){noformat} > The flush() call is testRecover() should fail, because we restart one of the > DN in the DFS cluster which is expected to brake connection. It succeeds > though if the preceding test already restarted a DN. No matter which DN we > restart, even if they're different, the error occurs. > I also tried to add CLUSTER.waitDatanodeFullyStarted() at the end of > testConnectToDatanodeFailed(), looks like it made the tests slightly more > stable, but didn't help fully. -- This message was sent by Atlassian Jira (v8.20.10#820010)
